Answer:
D. 
Step-by-step explanation:
Consider the set

This set consists of four ordered pairs.
The first numbers in these pairs are
These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are
These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and

Answer:
-4
Step-by-step explanation:
g(2) means x=2

△ABC right angle C, leg BC > leg AC. So angle A > angle B.
a=BC, b=AC, c=AB
a > b
sin A= cos B = a/c
sin B = cos A = b/c
a = c sin A = c cos B
b = c sin B = c cos A
a > b
c sin A > c sin B
sin A > sin B
c cos B > c cos A
cos B > cos A
Answer: B, E
